This example shows a dataset summary and an SVG bar chart of total workout minutes grouped by intensity level, based on a CSV file of workout entries fetched from a remote URL. The page uses D3 v7’s `d3.csvParse`, `d3.rollups`, `d3.sum`, and `d3.scaleBand` with `d3.axisBottom` and `d3.axisLeft` to build the chart. It also displays file size, row and column counts, and a preview table of the first six rows.
